Live Location- The immediate, real-time position of a worker or responder on a map. 

Location Awareness- Location awareness refers to the ability of a system or platform to understand and display the precise position of personnel, assets, or equipment in real time. It provides commanders or supervisors with immediate visibility into where individuals are located across a job site, incident scene, or facility. 

Location Map- A digital map showing the positions of workers, assets, or crews in real time. 

Location Monitoring- Continuous observation of worker or responder position and movement for safety and operational awareness. 

Location Tracking- The broad term for determining and displaying the current location of personnel, equipment, or vehicles.
